A CORPORATION OF NEW YORK DISPENSING'CLOSURE FOR onus Application filed August 22, 1931. Serial No. 558,814.

The invention relates to new and useful improvements in a dispensing closure for containers, that is, aclosure which may be relnovably attached to a container after it has been opened for the purpose of providing a closure for the container with a movable section through. which access may be had to the contents of the container when desired.

An object of the invention is to provide a dispensing closure wherein the top portion having an opening closed by a cover section is attached to a collar adapted to frictionally engage the friction seat on the container by an interfolding of the metal parts of the collar and the closure top so as to form a very rigid closure structure, wherein the edges are concealed and there is no necessity for the use of an extensive solder bond for joining the parts.

In the drawing:

Fig. 1 is a sectional view through the closure showing the same attached to a container.

Fig. 2 is a plan view of the closure detached from the container and with the cover partly raised.

Fig. 3 is an enlarged vertical sectional view through a portion of the closure.

Fig. 4 is a view similar to Fig. 3 but showing a slightly modified shaping of the parts so that the closure overlies the double seam.

The invention is directed to a dispensing closure for containers which isreadily attached to the container after it has been opened. The dispensing closure includes a top portion having a depending flange adapted to frictionally engage the friction seat of the container after the friction plug closure has been removed therefrom. This top portion is provided with an opening which is concentric to the outer edge of the closure throughout a portion of the circumference and which has a straight side lying on a chord of the circular circumference. This opening is closed by a removable cover which is hinged to the top portion by a hinge lying along the straight side of the opening. The lower edge of the depending flange is rolled inward so as to provide a head which strengthens the lower edge and facilitates the attachment of the closure to the container.

-Referring more in detail to the drawing, the invention is shown as applied to a container having a body portion 1 and a top portion 2 which are joined by double seaming as indicated at 3. Said top portion is provided with an opening with a depending vertical friction seat l surrounding the opening. This is the usual form of closure with a single friction seat. The opening of the container is closed by a friction plug cover which engages this friction seat 4:. The friction plug is pried out and thus the container is opened. The present invention has particularly to do with a dispensing closure for this opening after the friction plug cover has been re-. moved. The closure includes a top portion 5; said top portion 5 has an opening formed therethrough which is circular as indicated at @390, and this circular portion is concentric to the outer edge of the closure. There is also a straight side to the opening which is indicated at a, ti, o. The edge a, b, a of the metal in the top forming this openingy which is indicated by the numeral 6, is rolleddownward and outward to form a head 7. The metal in the top is alsorolled upward and into an open bead or hinge lug along the straight edge and these hinge lugs are indicated at 8, 8 in the drawing.

The opening 6* is adapted to be closed by a cover 6 which is of sulficient dimensions so as to rest onthe ledge 9 of the top and substantially cover the same. 'In other words, the outer circular dimensions of the cover are substantially the same as the outer circular dimensions of the closure. The cover is provided with upwardly hollow rolled beads or hinge lugs 10,.10... These hinge lugs are staggered relative to the hinge lugs 8 anda rod 11. passes through the hinge lugs joining the cover to the top portion of the closure. The-cover has-a handle 12 which maybe of any desired shape. As shownv in the drawing, the top portion is made separately from V a depending collar 13. This collar is bent outwardly at its upper edge portion to form a horizontal flange 14. The cover is bent downwardly and inwardly underneath the flange let as indicated at 15. The lower edge portion of the collar 13 is rolled inwardly and upwardly to form a bead 16. This depending collar 13 is thus rigidly attached to the top of the closure and is the means which engages the friction seat 4 on the container body. p

It will be noted that the top of the closure has a smooth edge due to the fact that it is f folded underneaththe flange on the collar. This interfolding and connecting of the parts forms a very rigid closure structure and one where there are no exposed edges "of metal. Furthermore, by this interfolding connection between the top and the collar, the portions projecting outwardly from'the'collar 13 may be extended so as to overly and contact with the double seam of the container as-shown in Fig. 4 of the drawing; In this figure the closuretop has a raised portion which brings the cover to a position above the plane of the double seam.

It is obvious that changes may be made in the construction without departing from the scope of the appendedclaims.
